Abstract

A simplified record player constructed such that the driving force from a motor is transmitted through a drive shaft to a tubular shaft which is capable of being coupled to the drive shaft so as to be rotated therewith, but only in the direction of rotation. The tubular shaft is normally biased in an axial direction away from the drive shaft. The tubular shaft has facing downwardly a directed stepped portion formed at its outer periphery. A latch shaft having an upper end face, an annular flange formed at its outer periphery and an upwardly facing stepped portion is fitted about the periphery of the tubular shaft. A coil spring supported by a washer is disposed around the tubular shaft and urges the latch shaft at the flange such that the stepped portion of the latch shaft abuts against the stepped portion of the tubular shaft. A push button is mounted to the top of the tubular shaft and includes within its interior a plurality of roller-type record retaining pieces. The retaining pieces are resiliently and partially projected from the interior of the push button toward the outside so as to clamp a record disc. A latch piece is swingably attached to the record player housing and is normally biased toward the axis of the shaft assembly such that it engages the latch shaft flange when the push button is not pushed down and acts to prevent the tubular shaft and the latch shaft from separating.
